Taiwan confirms first autonomous AI-agent cyberattack on government networks

Attack discovery and confirmation

Taiwan's Ministry of Digital Affairs confirmed on August 13, 2026 that its cybersecurity monitoring units detected an "abnormal attack" targeting government agencies in July. Beginning July 20, the National Institute of Cyber Security issued a series of warning alerts while investigating the incident. The ministry said the attacks displayed clear characteristics of an "overseas source," with hackers employing a hybrid approach combining manual operations with AI agent-assisted attacks such as OpenClaw. The affected units had "successively completed their handling," the ministry said, adding that attack sources, methods, and scope of impact had all been fully investigated. The statement did not mention China.

The confirmation followed a report by the Financial Times on August 12, 2026, covering research by Dream, an Israeli cybersecurity and AI company. Dream said it uncovered the AI-driven campaign during routine monitoring of cybercriminal activity, finding a 160MB online archive of 1,395 files that documented the operation. A person familiar with the attack confirmed to The Register that Taiwan was the target.

How the autonomous attack worked

According to Dream, the attackers built a largely autonomous hacking tool from two open-source AI agents, Hermes and OpenClaw. The system deployed up to eight sub-agents simultaneously, each with its own targets and techniques, across 12 "attack waves" conducted between July 1 and 4. The agents first mapped the government ecosystem, extracting embedded URLs, API access points, client IDs, and Keycloak configuration objects from a single government portal. This allowed them to identify 21 connected government systems and probe each for vulnerabilities.

The AI agents conducted reconnaissance and intrusion independently, chaining vulnerabilities and changing tactics whenever blocked. The hackers framed the intrusion context as a routine cyber readiness test to bypass the AI models' built-in guardrails. Over four days, the attack compromised 85 government user accounts and extracted over 2,500 personnel records from Taiwan's justice ministry before expanding to target Taiwan's nuclear safety agency and at least seven energy companies.

Attribution and evidence

Dream did not attribute the attack to a specific hacker group or confirm the target. However, documentation within the recovered archive contained Simplified Chinese, the official written language of mainland China, which Dream said indicated a high probability of an operator connected to the People's Republic. Data collected from targets was written in Traditional Chinese, used in Taiwan, Hong Kong, and Macau. The Financial Times reported that hackers linked to China were suspected.

Broader threat landscape

Chinese cyberattacks on Taiwan's critical infrastructure, from hospitals to banks, rose 6% in 2025 from the previous year, reaching an average of 2.63 million attacks per day, Taiwan's National Security Bureau reported in January. Some attacks were synchronized with military drills in what the bureau described as "hybrid threats" designed to paralyze the island. China considers Taiwan part of its territory and has intensified military, diplomatic, and propagandistic pressure on the democratically governed island.

The disclosed case follows reports that AI systems from US companies Anthropic and OpenAI have independently executed successful network attacks without their developers' consent in recent weeks. Dream's researchers wrote that they did not believe governments were prepared for this new type of threat, noting that such an orchestrated AI-agent attack on a government target had not been previously observed.

This must be the basic assumption of every government around the globe.
